La métrologie, c’est la science de la mesure. Dit comme ça, cela paraît abstrait, voire anodin. Pourtant, sans elle, rien ne fonctionne : ni l’industrie, ni le commerce, ni la médecine, ni même le numérique. C’est elle qui garantit que le temps, le poids, la température, la tensi ... Show More

Imaginez une balle posée contre un mur vertical. À l’arrêt, elle tombe. Classique. Mais maintenant, imaginez qu’elle commence à grimper toute seule, lentement mais sûrement, sans moteur, sans aimant, sans trucage. Ça semble impossible ? Et pourtant, c’est ce qu’ont réussi des che ... Show More

Tout le monde ou presque en a fait l’expérience : une balade en forêt, un frottement léger contre une plante anodine… et soudain, une brûlure, des démangeaisons, parfois des petits boutons rouges. Pas de doute : vous venez de croiser une ortie. Mais pourquoi cette plante, a prior ... Show More

A black hole is so dense, its gravitational field prevents anything from escaping, including light. You would think that would make them the "blackest" things in the universe; how in the world do we know they are there? Dr. Andrea Derdzinski tells us about how we detect black hol ... Show More

Black holes are inescapable traps for most of what falls into them — but there can be exceptions. The theoretical physicist Leonard Susskind speaks with co-host Janna Levin about the black hole information paradox and how it has propelled modern physics. The post Can Information ... Show More

Have black holes existed since the beginning of the Universe? Could we produce a black hole in the lab? Could we use gravitational waves to probe beyond the event horizon?  It's a black hole Q&A as Izzie put your questions to Becky and Robert. Plus, author and broadcaster, Marcus ... Show More

Black holes are objects that seem exotic to us because they have properties that boggle our comparatively mild-mannered minds. These are objects that light cannot escape from, yet glow with the energy they have captured until they evaporate out all of their mass. They thus have t ... Show More

Black holes are one of the most beguiling objects in our universe. What are they exactly? How do they affect the universe? And what would it be like to fall into one? We venture beyond the point of no return with Yale astrophysicist Priyamvada Natarajan, into a fascinating world ... Show More
